Mail box device for dwelling, has illuminating device controlled by microcontroller based on surrounding luminosity and mounted near or at holder by being protected against atmospheric action such as rain

摘要

#CMT# #/CMT# The device (1) has mail box (2) comprising a front door (3) provided with a name or illuminated label holder (4). An autonomous power supply integrates renewable energy source (5) e.g. photovoltaic cell, and an electrical energy storage unit (6) e.g. rechargeable battery. A holder illuminating device (7) e.g. white LED, is supplied with the energy from the storage unit. The device (7) is controlled by a PIC(RTM: microcontroller) based on surrounding luminosity and mounted near or at the level of the holder by being protected against atmospheric action such as rain. #CMT#USE : #/CMT# Mail box device for a dwelling. #CMT#ADVANTAGE : #/CMT# The device is controlled by the microcontroller based on surrounding luminosity and mounted near or at the level of the holder by being protected against atmospheric action, thus reducing electrical energy consumption, and avoiding regular maintenance such as changing of component. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a perspective view of a mail box device with an operational sub-assembly forming an autonomous power supply in exploded state. 1 : Mail box device 2 : Mail box 3 : Front door 4 : Name or illuminated label holder 5 : Renewable energy source 6 : Electrical energy storage unit 7 : Illuminating device.
